Only at the spindle. The ST-25LY has a 10 in (254 mm) chuck, 3 in (76 mm) of bar capacity, 30 hp (22.4 kW), 300 ft-lbf (407 N·m) at 500 rpm and a 3,400 rpm maximum. The ST-20LY has an 8.3 in (210 mm) chuck, 2.5 in (64 mm) of bar capacity, 20 hp (14.9 kW), 150 ft-lbf (203 N·m) and 4,000 rpm. Travels, turning diameter and live-tool speed match.
The main spindle runs to 3,400 rpm, with peak torque of 300 ft-lbf (407 N·m) at 500 rpm. Live tools on the BMT65 turret run to 4,000 rpm. The C axis, used for positioning and for interpolated milling, turns at up to 60 rpm.
± 2 in (± 51 mm). That lets a live tool cut flats, slots and holes off the spindle centreline without rotating the part, which gives truer flat faces than C-axis interpolation alone. Y rapids are 472 ipm (12 m/min) and Y thrust is 2,300 lbf (10,231 N).
The spec table for this model has no sub-spindle rows. Plan on turning and milling one side of the part in the main chuck across 42.5 in (1,080 mm) of Z, and handling the second side as its own operation.
Either 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. Compressed air: 4 scfm at 100 psi (113 L/min at 6.9 bar), with 80 psi (5.5 bar) as the minimum pressure and 3/8 in for both hose and coupler. The machine weighs 12,360 lb (5,606 kg).
